Fig. 2From: Selection index theory for populations under directional and stabilizing selectionThe profit of the simulated population in generations 0 to 9 is shown for two selection indices. The conventional index includes only the animal’s EBV, while the optimum index also includes the frequencies of major QTL, the QTL heterozygosities, and the squared EBV. The optimum index maximizes the average profit in generations 1 to 9Back to article page
